The review suggests that implant use improved patient satisfaction and masticatory ability. However, these findings should be interpreted with caution.

This review of tooth preparation for crowns focuses mainly on the total occlusal convergence angle (TOC). The traditionally recommended 2-4 degree TOC was seen to be unachievable in the clinical situation.

While this review of zirconium restoration included 27 studies, only 5 were RCTs. Furthermore only 4 studies had more than 5 years follow up. Ten studies included fewer than 20 restorations, so while good survival data was presented, the results should be viewed with caution.

This review of survival rates of dental implants placed in fresh extraction sockets included 73 studies. However the majority were retrospective with only 5 small RCTs and 26 controlled trials. While the findings suggest that failure rates are higher in extraction sockets the evidence should be interpreted with caution.
